Stingless jellyfish edit

Snorkelling in the stingless jellyfish lake

Derawan Islands have at least two lakes containing stingless jellyfish, one in Kakaban Island and the other in Maratua Island with Haji Buang Pond. Kakaban is more famous than the second, which is also more difficult to access. The lake in Kakaban consists of millions of jellyfish, ranging from small to large ones, some, twice as big as an adult's palm. Indonesia has at least 7 lakes with stingless jellyfish. Some others are located in: Raja Ampat, West Papua, Togean Island, Central Sulawesi and one in Rote Island, East Nusa Tenggara.[1]

Resources use edit

There are two inhabited islands, namely Derawan (with a village of 1,259 people) and Maratua (comprising four villages with 2,704 people). Fishing is an important income-generating activity for the community. Since the early 1990s, people have caught live groupers, Napoleon wrasse, and lobsters, to fill high demand. There are three diving resorts in the Derawan Islands, while more additional resorts or facilities are in the planning process.

Caves edit

Maratua Island has an area of 35.5 square kilometers and has at least 13 caves, but the prediction is that there are more than a hundred caves which are not yet explored. The caves usually have connection directly to the sea. These caves originated from reef which sea water infiltrated into, creating underground channels.[2]
